Abstract
Abstract An uncased book is first prepared. The outside end papers on each of the top and bottom of the book consists of a sheet of paper, flexible plastic, cloth, or the like, coated with pressure-sensitive adhesive with the sensitive surface outermost and protected by a protective release covering scored in at least two lines adjacent to the inner edge. Spaced holes are punched, drilled or otherwise formed adjacent to the inside margin of each sheet of the book, including the end papers. A first narrow strip of plastic having projecting studs spaced the same as the holes and a second narrow strip formed with corresponding holes are provided. The studs are inserted through the holes in the endpapers, sheets and second strip and the strips forced toward each other, compressing the sheets there-between. The excess stud lengths are cut off and heads similar to rivet heads formed, securing the uncased book in assembled condition. A case is provided similar to conventional book cases. Initially such case has a central spine strip of double-face, pressure-sensitive material, one face adhered to the cover, the other covered by a detachable protective release strip. To assemble the book to the case, the first step is to remove the protective release strip from the spine strip, then to press the spine of the uncased book so that it adheres to the middle of the spine strip and to bend the excess width of the spine strip around the outside of the plastic strips. Next a narrow band of protective release cover is removed to expose about three-eighths inch of each end leaf immediately outside the plastic strips. The case is then creased to form spine beads and creases between the beads and the boards of the case. Finally, the remainder of the protective release covers are removed, causing the end leaves to be secured to the insides of the covers of the case.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
206 words
A cased book comprising an uncased book having a plurality of sheets, front and back end leaves on the outside of said uncased book, each said end leaf having pressure-sensitive material on its outer surface, and binding means binding said end leaves and sheets together so that said end leaves are securely bound to said sheets prior to assembly of said uncased book to a case; and a case for said uncased book having front and back covers, a flexible spine and covering means for the outsides of both said front and back covers and of said spine, said case prior to adherence to said uncased book being adapted to encase a range of thicknesses of uncased books by reason of the flexibility of said spine, said end leaves permanently adhering to the insides of said front and back covers by means of said pressure-sensitive material, said pressure-sensitive material extending to the outer edges of said end leaves, the outer edges of said covers extending outwardly beyond the outer edges of said end leaves, said indices of said covers being devoid of exposed adhesive beyond the outer edges of said end leaves, the spine edge of said uncased book being centered relative to said flexible spine.
Claim 2
Dependent Claim

Claim 4
Dependent Claim
307 words
A cased book comprising an uncased book formed of sheets each formed with a plurality of first apertures along the inner margins of said sheets, at least one front and back end leaf on the outside of said sheets each formed with a plurality of second apertures corresponding to the spacing of said first apertures, a first narrow plastic strip formed with a plurality of third apertures corresponding to the spacing of said first apertures and overlying one edge of one of Said end leaves adjacent to the inner edge of the side of said uncased book opposite said first plastic strip, means on the ends of said studs securing said studs to said first strip to form an uncased book, said end leaves each being provided with pressure-sensitive adhesive on its outer surface and initially protected by a removable protective cover, each said end leaf being securely bound between said plastic strips to said sheets; and a case for said uncased book having front and back covers and a flexible spine, and covering means for the outsides of both said front and back covers and of said spine, said case prior to adherence to said uncased book being adapted to encase a range of thicknesses of uncased books by reason of the flexibility of said spine, said end leaves permanently adhering to the insides of said front and back covers by means of said pressure-sensitive adhesive after said protective covers have been removed, said pressure-sensitive material extending to the outer edges of said end leaves, the outer edges of said covers extending outwardly beyond the outer edges of said end leaves, said insides of said covers being devoid of exposed adhesive beyond the outer edges of said end leaves, the spine edge of said uncased book being centered relative to said spine portion of said covering.
Claim 5
Dependent Claim
